One Piece, Vol. 2: Buggy the Clown by Eiichiro Oda and Andy Nakatani

As a kid, Monkey D. Luffy vowed to become King of the Pirates and find the legendary treasure called the "One Piece." The enchanted Gum-Gum Fruit has given Luffy the power to stretch like rubber--and his new crewmate, the infamous pirate hunter Roronoa Zolo, strikes fear into the hearts of other buccaneers! But what chance does one rubber guy stand against Nami, a thief so tough she specializes in robbing pirates...or Captain Buggy, a fiendish pirate lord whose weird, clownish appearance conceals even weirder powers? It's pirate vs. pirate in the second swashbuckling volume of One Piece!

zoro is still my husband

Friends made: Chouchou the dog, Boodle mayor of Port Town, Nami?? (by Luffy reckoning definitely.)
Enemies defeated by Luffy: Mohji the Lion Tamer (Buggy's first mate)
Enemies defeated by Zoro: Cabaji the Acrobat (Buggy's second mate)

Thoughts-
1. Lots of badass Zoro traits revealed. His extreme physical strength, pain tolerance, napping off what should be mortal wounds, and deliberately wounding himself to prove how good he is.
2. Luffy hits his friends a lot lol. Cody a bunch in the first volume and the mayor in this one. All for their own good of course.
3. One Piece makes it easy to forget how evil some of the characters were when they're first introduced. Buggy blows up his own crew member for a perceived slight, chokes the old mayor nearly to death (if Luffy hadn't intervened) and more. But I'm so fond of him!
